Detailed Description
The embodiment of the application provides a control method for a throttle valve plate, and solves the technical problem that in the prior art, freezing and clamping stagnation are easy to occur between the valve plate of the throttle valve and a throttle valve shell, so that the probability that an automobile cannot be normally started is high.
In order to solve the technical problems, the general idea of the embodiment of the application is as follows:
a throttle valve sheet control method includes: the method comprises the steps of acquiring the current temperature of the environment where a vehicle is located when an engine of the vehicle is in a stopping process; judging whether the current temperature is less than or equal to a preset temperature or not; if the current temperature is less than or equal to the preset temperature, determining a target deflection angle corresponding to the throttle valve plate 1 according to the current temperature; and controlling the throttle valve plate 1 of the engine to deflect a target deflection angle.
According to the embodiment, whether the throttle valve has the possibility of icing is determined according to the current temperature of the environment where the vehicle is located when the engine of the vehicle is stopped, and when the possibility of icing exists, the target deflection angle of the throttle valve which needs to deflect is determined according to the current temperature, so that the deflection target deflection angle of the throttle valve block 1 is controlled, the probability of icing and clamping stagnation of the throttle valve block 1 is reduced, the normal starting probability of the vehicle is improved, and the user experience is improved.
In order to better understand the technical scheme, the technical scheme is described in detail in the following with reference to the attached drawings of the specification and specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The air in front of the throttle valve is derived from the air filter (or the steam compressor end of the supercharger), and the air behind the throttle valve enters the engine intake manifold to be mixed with the air flow of the engine intake manifold. Under the condition of low temperature, for example, about minus 30 ℃, the air temperature of an automobile engine throttle is often too low, so that the probability that the automobile cannot be started normally due to freezing and clamping of the throttle is high. As shown in FIG. 1, which is a schematic sectional view of a throttle valve (the left side in the figure is the end where an intake manifold is located), a position where a throttle valve sheet 1 and a throttle housing 2 are frozen in a normal case is indicated as a position A in FIG. 1.
In order to solve the above problem, the present embodiment provides a throttle valve sheet control method as shown in fig. 2, which includes steps S21 to S24.
S21, acquiring the current temperature of the environment of the vehicle in the stopping process of the engine of the vehicle;
step S22, judging whether the current temperature is less than or equal to a preset temperature;
s23, if the current temperature is less than or equal to the preset temperature, determining a target deflection angle corresponding to the throttle valve plate 1 according to the current temperature;
and step S24, controlling the throttle valve plate 1 of the engine to deflect a target deflection angle.
With regard to step S21, the current temperature of the environment in which the vehicle is located is acquired while the engine of the vehicle is in a stopped state.
When the vehicle engine is in the running process, high-temperature gas can also pass through the throttle valve due to the fact that the temperature of the engine is high, and therefore the throttle valve cannot be frozen due to the fact that the external temperature is low.
After the engine is switched to the shutdown process from the operation process, the heat of the engine can be consumed along with the lapse of time, the temperature of the throttle valve can be the same as the ambient temperature finally, when the ambient temperature is at or below the freezing point temperature, the throttle valve can be frozen very possibly, the throttle valve plate 1 is blocked, and the next normal starting of the vehicle is influenced.
Therefore, in actual operation, only the influence of the ambient temperature on the throttle valve when the vehicle engine is in a stop state can be considered, and the influence of the ambient temperature on the throttle valve when the engine is in an operation state does not need to be considered.
Because the ambient temperature of the environment where the vehicle is located has direct influence on whether the valve plate of the throttle valve is frozen and stuck, the embodiment relies on the temperature sensor of the vehicle itself to detect the current temperature of the environment where the vehicle is located for the use of the subsequent steps.
With respect to step S22, it is determined whether the current temperature is less than or equal to a preset temperature.
The possibility of freezing of the throttle valve can be determined in advance based on the relationship between the current temperature of the environment in which the vehicle is located and the preset temperature.
The step of determining the preset temperature comprises the following steps:
in step S31, an environmental parameter of an environment in which the vehicle is located is acquired.
And step S32, determining the freezing point temperature according to the environmental parameters.
And step S33, determining a preset temperature according to the freezing point temperature.
The environmental parameter may include at least one of an altitude, an atmospheric pressure, at which the vehicle is currently located. The freezing point temperature of the current position of the vehicle can be determined according to the environmental parameters, and specifically can be determined according to the relationship between the altitude and the freezing point temperature in the related art, or according to the relationship between the atmospheric pressure and the freezing point temperature, which is not described in detail in this embodiment.
The preset temperature can be determined according to the freezing point temperature, the preset temperature can be determined according to +/-N ℃ of the freezing point temperature, N can be an integer or a non-integer, and N can be set according to actual conditions. For example, when the freezing temperature is 0 ℃, N may be 1, and the predetermined temperature may be selected from the range of-1 ℃ to +1 ℃.
If the current temperature of the environment where the vehicle is located is higher than the preset temperature, the possibility of throttle valve icing is low, namely the possibility that the vehicle can be normally started at the next starting is high, and anti-icing treatment is not needed.
If the current temperature of the environment in which the vehicle is located is less than or equal to the preset temperature, the throttle valve is more likely to be frozen, and step S23 and step S24 need to be continuously executed to reduce the occurrence probability of the phenomenon that throttle valve sheet 1 is stuck due to freezing.
With respect to step S23, if the current temperature is less than or equal to the preset temperature, the target deflection angle corresponding to throttle valve plate 1 is determined according to the current temperature.
Specifically, the target deflection angle may be determined according to a preset incidence relation between the ambient temperature and a preset deflection angle of the throttle valve plate 1 and the current temperature.
The preset correlation between the ambient temperature and the preset deflection angle may be: the higher the representation ambient temperature is, the larger the preset deflection angle is, the continuous relation or discrete relation. For example, the ambient temperature is in direct proportion to the preset deflection angle, or the ambient temperature is divided into a plurality of temperature segments, and for each temperature segment, the higher the temperature corresponding to the temperature segment is, the larger the corresponding preset deflection angle is.
As shown in fig. 3, the preset temperature is 0 ℃, and if the current temperature is 0 to-10 ℃, the corresponding preset deflection angle is 5 degrees; if the current temperature is between-10 ℃ and-20 ℃, the corresponding preset deflection angle is 10 degrees; if the current temperature is in the range of less than-20 deg.c, the corresponding preset deflection angle is 15 deg..
The target deflection angle corresponding to the throttle valve plate 1 can be determined according to the current temperature and the preset correlation, for example, taking fig. 3 as an example, if the current temperature is-15 ℃, the corresponding preset deflection angle is 10 °, that is, the target deflection angle is 10 °.
With respect to step S24, the throttle valve plate 1 of the engine is controlled to deflect by the target deflection angle.
After the target deflection angle is determined, the throttle valve plate 1 is controlled to deflect the target deflection angle. When the throttle valve sheet 1 is not deflected, it is in the position shown in fig. 1, and when the throttle valve sheet 1 is deflected, it is in the position shown in fig. 4 (mainly, the position shown in fig. 1 is the original position, and the position shown in fig. 4 is obtained after clockwise rotation). When the throttle valve plate 1 deflects, the throttle valve plate 1 and the throttle housing 2 are not contacted, and the larger the distance between the throttle valve plate 1 and the throttle housing 2 is, the smaller the possibility of icing and clamping of the throttle valve plate 1 and the throttle housing 2 is.
When the engine is in a shutdown state, the throttle valve plate 1 is controlled to deflect a target deflection angle, so that the probability of occurrence of the phenomenon that the throttle valve plate 1 is frozen and clamped can be greatly reduced, the probability of normal starting of the vehicle is greatly improved, and the user experience is improved.
It should be noted that, in the related art, when the engine is in the process of stopping, the valve plate of the throttle valve is in contact with the throttle housing 2, that is, the throttle valve plate 1 is in the closed state (as shown in fig. 1), and if the throttle valve is not closed after the engine is stopped, a throttle failure signal is generated. Since the throttle valve needs to be actively controlled to be in the open state in this embodiment, it is necessary to avoid generating a throttle failure signal or masking a throttle failure signal when implementing this embodiment.
In summary, in the embodiment, when the engine of the vehicle is in the stop process, whether the throttle valve has the possibility of icing is determined according to the current temperature of the environment where the vehicle is located, and when the possibility of icing exists, the target deflection angle, which the throttle valve needs to deflect, is determined according to the current temperature, so that the deflection angle of the throttle valve plate 1 is controlled, the probability of icing and clamping stagnation of the throttle valve plate 1 is reduced, the probability of normal start of the vehicle is improved, and the user experience is improved.
On the basis of the above scheme, the present embodiment further provides the following optimization scheme.
Specifically, after controlling the throttle valve plate 1 of the engine to deflect the target deflection angle, the method further includes steps S41 to S44.
Step S41, updating the current temperature of the environment where the vehicle is located;
step S42, judging whether the updated current temperature is less than or equal to a preset temperature;
step S43, if the updated current temperature is less than or equal to the preset temperature, re-determining the target deflection angle according to the updated current temperature;
and S44, controlling the throttle valve plate 1 to deflect according to the target deflection angle after redetermination.
After step S24 is performed, the ambient temperature in which the vehicle is located may change as time passes. For example, the vehicle is parked during the day and the ambient temperature around the vehicle decreases by night. The vehicle is parked at night and by day the ambient temperature around the vehicle increases.
In order to further reduce the negative influence of the environment temperature on the throttle valve, the environment temperature can be monitored, the current temperature of the environment where the vehicle is located is continuously updated according to a preset frequency, and the target deflection angle is readjusted according to the updated current temperature, so that the deflection angle of the throttle valve plate 1 can change along with the change of the current temperature of the environment where the vehicle is located.
For example, when the ambient temperature gradually decreases, the target deflection angle may gradually increase to reduce the probability of the occurrence of the freezing and sticking phenomenon of the throttle valve sheet 1. When the environmental temperature gradually rises, the target deflection angle can be gradually reduced so as to reduce the energy consumption of the throttle valve plate 1 in the opening state and reduce the probability of the throttle valve plate 1 in freezing and clamping stagnation.
In the parking process, because ambient temperature is lower, there may be icing phenomenon in the throttle casing 2, when the vehicle needs restart, throttle valve piece 1 can't close totally for unable normal start.
To solve this problem, during the restart of the engine, the method further comprises: and controlling the throttle valve plate 1 to swing within a preset angle range.
The throttle valve plate 1 is controlled to swing within a preset angle range, and ice in the throttle housing 2 can be removed through the swing of the throttle valve plate 1. The preset angle range can be set according to actual conditions.
In the process of controlling the swing of the throttle valve plate 1 within the preset angle range, the method further comprises the steps S51-S53.
In step S51, the actual swing range of the throttle valve sheet 1 is acquired.
Step S52, determining whether ice exists on the throttle housing 2 of the throttle valve according to the actual swing range and the preset angle range.
And S53, if the ice blocks exist on the throttle valve shell 2, controlling the throttle valve plate 1 to continuously swing within the preset angle range until the ice blocks on the throttle valve shell 2 are broken.
If icing occurs in the throttle valve housing 2, the throttle valve sheet 1 is likely not to be completely closed, and when the throttle valve sheet 1 swings, although the throttle valve sheet 1 is set to swing within a preset angle range, due to the blockage of ice, the actual swing range of the throttle valve sheet 1 is likely not to reach the maximum angle of the preset angle range. In order to be able to determine whether the throttle valve plate 1 is blocked by ice, it is possible to determine whether ice is present on the throttle housing 2 based on the difference between the actual swing range of the throttle valve plate 1 and the preset angle range. If no ice exists, the throttle valve plate 1 can be controlled to stop swinging, so that the vehicle can be started normally. If ice exists, the throttle blade 1 is controlled to continue swinging within the preset angle range until the throttle blade 1 can be closed with the throttle housing 2.
In addition, the valve plate 1 of the throttle valve can deflect based on motor drive, the motor drive needs to depend on electric energy, if the valve plate 1 of the throttle valve is in a deflection state for a long time, the energy consumption of the valve plate cannot be ignored, and therefore in the process that an engine of a vehicle is stopped, the electrifying time of the valve plate 1 of the throttle valve driven by the motor in the deflection state is monitored; and if the electrifying time length is equal to the preset time length, controlling the motor of the throttle valve to be powered off. The preset duration can be determined according to the residual electric quantity of the vehicle storage battery.
In summary, in the embodiment, when the engine of the vehicle is in the stop process, whether the throttle valve has the possibility of icing is determined according to the current temperature of the environment where the vehicle is located, and when the possibility of icing exists, the target deflection angle, which the throttle valve needs to deflect, is determined according to the current temperature, so that the deflection angle of the throttle valve plate 1 is controlled, and the probability of icing and clamping of the throttle valve plate 1 is reduced. In addition, the air throttle valve plate 1 is controlled to swing within a certain range, ice cubes on the air throttle shell 2 can be removed, the normal starting probability of the vehicle is further improved, and therefore user experience is improved.
